python将图片转换为base64

脚本转换

# 二进制方式打开图片文件
import base64

f = open(r"C:\Users\Admin\Desktop\新建文件夹 (2)\Snipaste_2022-09-03_21-08-19.png", "rb")

#读取文件的内容转换为base64编码
ls_f = str(base64.b64encode(f.read()))
bs_f = open(r"C:\Users\Admin\Desktop\新建文件夹 (2)\bs.txt","w+")
bs_f.write(ls_f)
print(ls_f)
f.close()

前端转换

# Base64 Encoder - encodes a folder of PNG files and creates a .py file with definitions
import PySimpleGUI as sg
import os
import base64

    将图片转换为base64格式
    先选择存放图片的文件夹
    然后会生成一个outpt.py文件夹。里面存放了转换后的内容。用sublime打开。
    input:  folder with .png .ico .gif 's
    output: output.py file with variables
